在使用具有类别的SKSpritenode时，找不到Sprite的纹理，未显示Sprite

Question

我开始使用SKSpritenode类别系统来扩展SKSpriteNode的基本功能，并且现在通过编辑器添加到.sks场景中的精灵（不是从场景中丢失）在运行时到达场景。当我在.sk上记录一些精灵时，我可以看到它们的正确位置和比例参数，但是Xcode的调试控制台中的纹理总是['nil']。发生这种情况时（请参见下面的NSlog行），例如，当我在gamescene1.sk上名为" house1"的日志元素时，命名为" house1" sknoe。在场景编辑器上，我可以看到所有元素（包括该house1 element）罚款，但是当我启动项目时，都没有显示出.sks文件中的精灵。这是相关代码：

GamesScene头文件是：

//GameScene.h
#import "Hero.h"
#import "SKSpriteNode+StaticLevelElement.h"
@interface GameScene : SKScene <SKPhysicsContactDelegate>
-(void) initStaticLevelElements;
@end

GamesScene实现文件是：

//GameScene.m
#import "SKSpriteNode+StaticLevelElement.h" 
@implementation SKScene (Unarchive)
+ (instancetype)unarchiveFromFile:(NSString *)file {
    /* Retrieve scene file path from the application bundle */
    NSString *nodePath = [[NSBundle mainBundle] pathForResource:file ofType:@"sks"];
    /* Unarchive the file to an SKScene object */
    NSData *data = [NSData dataWithContentsOfFile:nodePath
                                      options:NSDataReadingMappedIfSafe
                                        error:nil];
    NSKeyedUnarchiver *arch = [[NSKeyedUnarchiver alloc] initForReadingWithData:data];
    [arch setClass:self forClassName:@"SKScene"];
    SKScene *scene = [arch decodeObjectForKey:NSKeyedArchiveRootObjectKey];
    [arch finishDecoding];
    return scene;
}  
@end
@implementation GameScene
-(void)didMoveToView:(SKView *)view {
    //Overriden in each level scene
    [self initStaticLevelElements];
}
-(void) initStaticLevelElements {
}
@end

gamescene1.m是：

//  GameScene1.m
#import "GameScene1.h"
#import "Customer.h"
#import "Competitor.h"
@implementation SKScene (Unarchive)
+ (instancetype)unarchiveFromFile:(NSString *)file {
    NSString *nodePath = [[NSBundle mainBundle] pathForResource:file ofType:@"sks"];
    NSData *data = [NSData dataWithContentsOfFile:nodePath
                                      options:NSDataReadingMappedIfSafe
                                        error:nil];
    NSKeyedUnarchiver *arch = [[NSKeyedUnarchiver alloc] initForReadingWithData:data];
    [arch setClass:self forClassName:@"SKScene"];
    SKScene *scene = [arch decodeObjectForKey:NSKeyedArchiveRootObjectKey];
    [arch finishDecoding];
    return scene;
}
@end
@implementation GameScene1
#include "GoodsConstants.h"
-(void) initStaticLevelElements {
    self.staticLevelElements = [[NSMutableArray alloc] init];
    self.name = @"name for scene one";
    SKNode * statics = [self childNodeWithName:@"statics"];
    statics.zPosition = 100;
    SKSpriteNode * e = (SKSpriteNode *)[statics childNodeWithName:@"house1"];
    NSLog(@"house one is: %@", e);
}

gamescene1.h是：

//  GameScene1.h
#import <SpriteKit/SpriteKit.h>
#import "GameScene.h"

@interface GameScene1 : GameScene
@end

skspritenode staticlevlelement.h是：

//  SKSpriteNode+StaticLevelElement.h  
#import <SpriteKit/SpriteKit.h>
#import <SpriteKit/SKSpriteNode.h>
@interface SKSpriteNode (StaticLevelElement)
-(void) initWithSKNode:(SKNode *)node;
@property NSNumber * pseudoDepth;
@end

skspritenode staticlevlelement.m是：

//SKSpriteNode+StaticLevelElement.m
#import <objc/runtime.h>
#import "SKSpriteNode+StaticLevelElement.h"
NSString * const pseudoDepthSelector = @"pseudoDepth";
@implementation SKSpriteNode (StaticLevelElement)
@dynamic pseudoDepth;
- (instancetype)initWithCoder:(NSCoder *)coder
{
    self = [super initWithCoder:coder];
    self.userInteractionEnabled = YES;
    return self;
}
- (void)setPseudoDepth:(NSNumber *)pseudoDepth
{
objc_setAssociatedObject(self, (__bridge const void *)(pseudoDepthSelector), pseudoDepth, OBJC_ASSOCIATION_RETAIN_NONATOMIC);
}
- (NSNumber *)pseudoDepth
{
    return objc_getAssociatedObject(self, (__bridge const void *)(pseudoDepthSelector));
}
-(void) touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {
}
-(void) touchesMoved:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {
}
@end

为了设置每个场景（级别）的特定数据，我使用基本游戏类别的继承 - 因此，我获得了gamescene1，gameScene2等。有人知道我缺少什么也能看到纹理吗？

Answer 1

我从Skspritenode staticlevlelement.m现在一切正常，现在显示纹理，而精灵都显示在屏幕上。
